Whats typical for some Toyo Open Country M/T 35's?

 

When I had 35" on my truck,I kept them at 38psi..If your truck is like mine,it will go 3-5 days setting in my driveway without being driven.This will cause a little flat spotting to occurr,and I would notice it when i would first pull out,until I traveled about 2-3 miles on the highway to smooth things out.At that time I ran 33-35psi,then tried 38psi,and noticed the flat spot effect was hardly noticable after being parked up for 3-5 days...Hope this helps...

 

As a rule of thumb, for daily driving I run my tires at about 80% of the maximum cold pressure as stated on the side of the tire. I keep my 35" Cepek FCIIs at 40# as max is 50#.

 

i'll check and see what the max is. thanks

 

so it says 65 cold max, which puts me at 52 (80%). wtf

 

I'd use about 50 as a starting point, if the ride is a bit harsh, back off a little. The upside to less air is a softer ride, the downside is poorer fuel economy.

You've got a E load range tire, 65 max is common. I've got a D load range because I don't haul a lot of weight and only tow heavy a couple times a year.

I had E range tires on a diesel truck I used to have, max was 65, I found if I had much less than 50 psi in them my fuel economy started going to sh*t.

 

i just checked they were at 39.

 

295/70/18 (34.57's) Trail Grapplers and I run them at 50 psi.

 

i have 315/65/20, i'll try 50 and maybe i get better mpg than 14.

 

I would say every tire is diferent and will difer further on specific vehicles based on the weight of the vehicle. I had 4, 33" Goodyear off road tires , installed on my truck by American Tire, and they put 50 psi in each, the side wall says up to 60psi.
